主讲人/Speaker：

Hong-Hao Tu graduated from the Physics Base of Wuhan University in 2003 with an undergraduate degree. He obtained his doctorate from the Department of Physics of Tsinghua University in 2009. He then conducted postdoctoral research at the Max Planck Institute for Quantum Optics in Germany and the University of Munich. His research field is quantum multi-body theory, and his research interests are mainly focused on exploring novel quantum states and developing analytical and numerical methods applied to quantum multi-body physics, including tensor networks, conformal field theory, and strictly solvable models.

摘要/Abstract:

Chiral spin liquids (CSLs) are exotic quantum phases of matter that exhibit intrinsic topological order and break time-reversal symmetry. Initially introduced as a candidate ground state in frustrated quantum magnets, CSLs have since been recognized as paradigmatic examples of strongly correlated quantum states with fractionalized excitations and anyonic statistics. In this talk, I will provide an overview of the historical development of gapped CSLs in two dimensions and discuss several different theoretical approaches for constructing model wave functions and microscopic Hamiltonians. These include the conformal field theory correlator approach, the Gutzwiller projected fermionic parton approach, and Kitaev’s honeycomb model and its generalizations. I will also discuss realistic models that may host non-Abelian CSLs.
